CHAPTER 2
DESIGN REQUIREMENTS
2-1
SELECTION OF STRUCTURAL SYSTEMS. The structural systems must
conform to all applicable DOD, NAVFAC, and other government criteria and guidance,
as well as industry standards and commonly accepted methods of practice. Consider
logical alternatives for the foundations and for the framing systems when selecting the
structural system. The following factors must be considered:
a.
Total Life Cycle cost effectiveness of the structural system (the design
life of the facility, and the maintenance costs over this period)
b.
Constructability
c.
Experience level and availability of local contractors and labor force
d.
Availability of materials at the project location
e.
Experience of inspection personnel
f.
Construction schedule and methods
g.
Site environment, including accessibility, climate, seismic hazard,
subsurface conditions, and wind velocity

GENERAL GUIDANCE.
2-2.1
Design Criteria. All structural design must be in accordance with UFC 1-
200-01 as modified below. The design of piers and wharfs must be in accordance with
UFC 4-150-01, Design: Piers and Wharfs. Since UFGS specifications are not normally
required in design-build construction, UFGS specifications listed in UFC 1-200-01 may
not apply to design-build projects. Where newer versions of the codes or standards that
are referenced in the International Building Code are available, the newer versions may
be used with the approval of the NAVFAC Facilities Engineering Command (FEC) or
Engineering Field Division / Engineering Field Activity (EFD / EFA).
2-2.1.1 Live Loads. Live loads used in the design of buildings and other structures
shall be the maximum loads expected by the intended use or occupancy but must in no
case be less than the minimum uniformly distributed or concentrated loads required by
Appendix B of UFC 3-310-01, Design: Structural Load Data. Appendix B of UFC 3-310-
01 includes Table 1607.1 from the IBC 2003, with additional Occupancies or Uses for
military facilities.
2-2.1.2 Snow Loads. Determine design snow loads according to Section 7 of ASCE
7, however the design roof load must not be less than that determined by Section 1607
of the IBC.
Ground snow loads to be used to determine the design snow loads for roofs are given in
the IBC for the continental United States and Alaska. UFC 3-310-01 provides ground
snow loads at specific locations within the United States to assist in the consistent
interpretation of the information contained in the IBC, and to facilitate the application of
UFC 1-200-01 to Department of Defense (DoD) Facilities at locations outside of the
United States.
